FUNCFLAGS 枚举

定义

命名空间:
System.Runtime.InteropServices.ComTypes
程序集:
System.Runtime.InteropServices.dll, mscorlib.dll, netstandard.dll

标识定义函数属性的常量。Identifies the constants that define the properties of a function.

此枚举有一个 FlagsAttribute 属性，允许按位组合成员值。

FUNCFLAG_FBINDABLE 4

支持数据绑定的函数。The function that supports data binding.
FUNCFLAG_FDEFAULTBIND 32

最佳表示此对象的函数。The function that best represents the object. 一个类型中只能有一个函数可以具有此特性。Only one function in a type can have this attribute.
FUNCFLAG_FDEFAULTCOLLELEM 256

允许进行一种优化，使编译器查找“abc”类型上名为“xyz”的成员。Permits an optimization in which the compiler looks for a member named "xyz" on the type of "abc". 如果找到这样的成员，而且该成员标志为默认集合的某元素的访问器函数，则生成对该成员函数的调用。If such a member is found, and is flagged as an accessor function for an element of the default collection, a call is generated to that member function. 可以对调度接口和接口中的成员使用；不能对模块使用。Permitted on members in dispinterfaces and interfaces; not permitted on modules.
FUNCFLAG_FDISPLAYBIND 16

作为可绑定函数显示给用户的函数。The function that is displayed to the user as bindable. 还必须设置 FUNCFLAG_FBINDABLE。FUNCFLAG_FBINDABLE must also be set.
FUNCFLAG_FHIDDEN 64

不应将此函数显示给用户，尽管它存在并且为可绑定函数。The function should not be displayed to the user, although it exists and is bindable.
FUNCFLAG_FIMMEDIATEBIND 4096

作为单独的可绑定属性映射。Mapped as individual bindable properties.
FUNCFLAG_FNONBROWSABLE 1024

该属性出现在对象浏览器而非属性浏览器中。The property appears in an object browser, but not in a properties browser.
FUNCFLAG_FREPLACEABLE 2048

将该接口标记为具有默认行为。Tags the interface as having default behaviors.
FUNCFLAG_FREQUESTEDIT 8

设置后，任何对设置此属性的方法的调用都首先导致对 IPropertyNotifySink::OnRequestEdit 的调用。When set, any call to a method that sets the property results first in a call to IPropertyNotifySink::OnRequestEdit. OnRequestEdit 的实现确定是否允许该调用设置属性。The implementation of OnRequestEdit determines if the call is allowed to set the property.
FUNCFLAG_FRESTRICTED 1

此函数不应该是可从宏语言访问的。The function should not be accessible from macro languages. 此标志适用于系统级函数或类型浏览器不应显示的函数。This flag is intended for system-level functions or functions that type browsers should not display.
FUNCFLAG_FSOURCE 2

该函数返回一个对象，此对象为事件的源。The function returns an object that is a source of events.
FUNCFLAG_FUIDEFAULT 512

类型信息成员是在用户界面中显示的默认成员。The type information member is the default member for display in the user interface.
FUNCFLAG_FUSESGETLASTERROR 128

该函数支持 GetLastError。The function supports GetLastError. 如果在函数过程中发生错误，则调用方可以调用 GetLastError 来检索错误代码。If an error occurs during the function, the caller can call GetLastError to retrieve the error code.
